The system has been implemented at the Shuibei International Center and the Shuibei Jinzuo Building since August. According to building management, the move was a response to persistent smoking in restrooms and frequent customer complaints.
The restrooms are equipped with smoke-sensing systems linked to electrochromic “smart glass” partitions. Under normal conditions, the glass remains frosted and opaque. However, if the sensor detects cigarette smoke inside the stall, it triggers an electric current that instantly renders the glass transparent. Management states this allows staff to “detect and control” the situation immediately. They also claim that the pilot program has been widely recognized and significantly effective in deterring smokers. Consequently, there are plans to expand the installation throughout both buildings.
This initiative has sparked a large debate online, while some citizens support the strict anti-smoking stance, others argue that it may invade personal privacy.
Legal experts cited by local media outlet have raised concerns regarding the legality of the measure. While malls have the right to manage smoking in public areas, lawyers argue that restrooms are private spaces. Using such technology could violate an individual’s right to privacy and dignity. Furthermore, experts warned that technical malfunctions or false alarms could lead to innocent users being exposed, increasing the liability for the property management.
